Question

I do not know why it is proving to be so difficult, but basically I want to animate an NSView across my screen, and once it is done that animation, remove that NSView. It however seems that I can find absolutely no reference on how to do this. Can someone please help?

I am starting my animation like this

NSRect frame = blob.frame;
frame.origin.x = animationStopX;
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:timeToDisappear];
[[blob animator] setFrame:frame];
[NSAnimationContext endGrouping];

I have no way of getting a callback from this once it completes or anything.

Right after your beginGrouping statement, add this:

[[NSAnimationContext currentContext] setCompletionHandler:^{
        [self.blob removeFromSuperview];
    }];

setCompletionHandler: is a method in the NSAnimationContext class.
